Last night's BA105 managed to get to DXB a bit early 06:37, rather than 07:00, the revised arrival time. So that led to a slightly more leisurely turnaround for BA104 and a more or less on time - but retimed - departure on 08:36. Now ba.com/flightstatus suggests an arrival at 13:09, which would be probably good enough but I imagine the flight crew may find a few of those mystical short-cuts on the way back to London. I think the route still has a few places that they have to skirt around. But right now she is over Cairo.
